DB crash

We had a DB crash and although we had backups, rebuilding the content and tracking down the error took some time. It seems that the crash was due to some problem of Drupal handling trigger actions whenever a comment is posted. Comments are now available again, but i'm not immediately notified via email anymore.
Anyway, most of the stuff has already been restored and should work as expected. Some parts such as the forum still need to be fixed, though. If something isn't working as expected please contact me. Thx!
